IAN KENNEDY took advantage of Arizona's early offensive outburst.

Gerardo Parra hit his first career grand slam to cap a five-run second inning and the Diamondbacks beat the visiting Atlanta Braves, 6-4, Sunday, snapping a five-game losing streak.

The Phillies open a three-game series at Arizona Monday night.

"It's nice having a 5-1 lead going into the third inning," said Kennedy (3-0). "You can be a little more aggressive with the guys in the middle of the lineup."

Atlanta had won five in a row.

"We ran into a hot ballclub," said Arizona manager Kirk Gibson. "This feels pretty good. It makes you smile. It's been a while since we've shaken hands after a game."

Randall Delgado (2-1) retired the first two Arizona batters in the second. Jason Kubel then singled, Cody Ransom doubled and John McDonald was intentionally walked to load the bases. Delgado walked Kennedy on four pitches before Parra hit a drive into the pool area beyond the right-centerfield fence for a 5-1 lead.
